CHARLES SPRINGER, 0F ALBANY, NEW-YORK..

WELDING-TORCH.

To all rcito/mI 'it may concern:

`Be it known that I, CHARLES SPRINGER, a citizen ot' the United States, residing at' the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in lVelding-Torches, of which the following is a specification.

My invention relates to welding torches and the objects of my invention are to construct a welding torch by which the oxygen will iiow through a tube located inside oli the torch proper and the acetylene gas Afnter through a separate tube into the chamfoin the outside shell or casing of ie body torch inclosing the tube containing the oxygen gas and the acetylene as will enter the neck ofthe nozzle from aid chamber forming the body ot the torch, he acetylene gas enters from the said chamber tiret into a secondary chamber 'formed by a groove at the end of the body of the torch where. it is joined to the neck of the nozzle and flows through ports into the passage way in the neck and is mixed with oxygen gas in the neck ot the nozzle, while the oxygen gas will enter saidV neck from the central tube and the mixture ot' the two gases in proper proportion is discharged through the nozzle for the purpose of fusing the metals together for welding purposes.

@ther objects ot my invention will appear from thel specifications and drawings.

l accomplish these objects by means of the mechanism illustrated in the accompanying drawings, in which Figure l is a longitudinal ysection of my welding torch showing the method of mixing the two gases. Fig. is an elevation of the torch. Fig. B is the mixing chamber showing the ports and passageways of the gases into the nozzle. Fig. t is across section ot the torch upon line .lt-. Fig.

Similar letters refer to similar parts throughout the several views.

Referring to the drawings. A. represents a tube tor supplying oxygen gas to the torch.

The tube A. is much larger than the outlet through the neck to the nozzle. so to produce a greater pressure and tlow of gas through the nozzle than it' the tube was" ot the same size as the outlet through the nozzle. Surrounding thetube A. is the outside shell or casing olE the body ot the torch Speccation of Letters Patent.

proper, forming a chamber B. Into this chamber the acetylene gas is conducted .from the source ot' supply by any suitable means.

is a valve for admitting oxygen gas into the tube A. and regulating the supply and llow of the oxygen gas, and D. is a valve for admitting acetylene gas into the chamber B., and tor regulating the supply and flow of the acetylene gas.

' E. is the nozzle through which the mix ture of acetylene gas and oxygen gas is dis charged upon the metals desired to be welded. i

F. is a neck 'through which the mixture ot acetylene gas and oxygen -gas passes for discharge through the nozzle E.

' G, is an obstruction or narrow opening in the neck F. through which the oxygen gas flows.

By referringk to the drawings it will be seen that the tube int-o which the oxygen gas passes trom-the source of supply, empties directly into the passageway within the neck F. and the acetylene gas is discharged, through ports H, H from chamber B. into a secondary chamber formed by a groove l. in the end of the body 'of the torch and from said secondary chamber through tapering ports into the passageway of the neck F. The acetylenev gas entersthe passageway F. at a point nearer the nozzle than where the oxygen gas enters said passageway. The force of flow of the oxygen gas being greater than the force of flow of the'acetylene gas l the oxygen gas will tend to create a vacuum and carry along with it the .acetylene gas and increase the force of low of the mixture. The ports through which the acetylene gas ows from the secondary chamber into the neck are cone shaped. The inside of said ports being tapering, the smaller end at the point where the acetylene gas enters the passageway ot 'the neck F.

The passageway in neck F. for thellow ot the oxygen gas from tube to the nozzle Fi. is madesmaller between the point where the neck F. connects with the tube A. and the point in said passage way where the acetylene was enters said Jassage way b7` said cone shaped ports, as shown in Fig. 3. The parts eon'ung together forming the "union ot' the body' ot' the torch with the neck F. by which the passageway between tube and the passageway through the neck F. join each other Jfor-the flow of the oxygen gas `into the nozzle and the ports for the chamber into the passage way in the neck F.

are ground smooth so as to make a tight joint.- These parts are held together by a union nut so as to make a tight joint. By having this joint ground all leakage is removed and the necessity for Washers is dispensed with. The ports are always open for the iiow of gas through them. y

Constructed in this Way the flow of gas is always reliable and uniform and of great force, and being mixed as above described, the mixture, together with the'force of the flow-Will oroduce best results. The torch is also light in Weight; the construction is simple, inexpensive and useful.

IV hat Iclaim as my invention and to secure by Letters Patent, is-

l. In a Welding torch having a nozzle, a

desire tube adapted tocontain oxygen gas; a casing surrounding said tube and forming a chamber adapted to containacetylene gas; said casing, chamber and tube together forming the body of the torch; a neck connecting the body of the torch to the nozzle thereof adapted to permit the flow of gas there-through from the said tube to the nozzle of the torch; a secondary chamber at the end of the body of the torch; ports leading from said secondary chamber to the passage-.way Within the said neck of the torch;

Said ports being cone shaped with"v the smaller endslconnectlng with the passageway in theA neck of the torch.

2. Ina welding torch having a nozzle, a

leading from` said secondary chamber .to

the passageway Within lthe said neck of the torch; said ports being co-ne shaped with the smaller ends connecting with the passage-way in the neck of the torch; theipassage way for the flow of gas through theneck of said torch being more `contracted and narrower at a pointbetween the inlet of tube and the inlet o-f acetylene gas inta said passage-way from said ports than the. other portions of said passage-way,` substantially as described and for the purposes set forth. In testimony whereof I aiiix `my signature in presence of two witnesses.
